#How to make an Arch Movement of an object in gdevelop
Am working on a short project when a ball is shot from an angle(auto move)
I want to have my aim sprite move in an arch form and when user press the mouse a ball is released for the aim at whatever position the aim is current at. Can you please help me be able to move the aim in an arch shape form? attached is rough sketch of what am trying to do. I only need help with moving the aim back and forth in an arch shape
